The doubly charmed pseudoscalar tetraquarks T-cc(;(s)over-bar(s)over-bar)++ and T-cc(;(d)over-bar<)(s()over bar)>(++)
The mass and coupling of the doubly charmed J(P) = 0(-) diquark-antidiquark states T-cc (s) over bar(s) over bar(++) and T-cc;(d) over bar<(s)over (++)(bar)(>) that bear two units of the electric charge are calculated by ...
The nonet of the light scalar tetraquarks: The mesons a(0)(980) and K-0*(800)
The spectroscopic parameters and partial decay widths of the light mesons a(0)(980) and K-0*(800) are calculated by treating them as scalar diquark-antidiquark states. The masses and couplings of the mesons are found in ...
